DEMOUNTABLE SUPPORT FOR BEDSPRINGS Filed Aug. 18, 1948 2 Sheets-Sheet 2 INVENTOR JOSEPH SHAPIRO fl/ZM ATTo EY Patented Mar. 28, 1950 UNITED STATES PATENT OFFICE 12 Claims.

This invention relates to beds and sofas and in particular is directed to the provision of supporting means for a bedspring whereby the same maybe readily adapted for use as a bed or a sofa.

The cumbersomeness of the conventional bed comprising the bedstead and spring (upon which the mattress is placed) restricts the use of such structure to a bedroom. Where it is desired particularly to provide a bed that does not occupy as much cubic footage as the ordinary bed or to provide a living room with a structure that may be utilized during the daytime for sitting and at nightime for sleeping; the structures used have been either cots or couches having inadequate springs or complicated structures of the folding character which are opened at night. Some of the latter devices are exceedingly intricate in construction and costly, especially where they are provided with strong, sound springs.

I have conceived of a means whereby a strong. sturdy bedspring may be readily, easily and cheaply provided with a set of supports of relatively simple construction, said supports being easily affixed or removed, so that a structure can be made available with minimum expense which afiords either seating or sleeping accommodations.

' Accordingly it is among the objects of this invention to provide a novel support of relatively simple construction which may be readily affixed to the frame of a, bedspring, whereby the bedspring is converted into a structure that may be used both as a seat and as a bed.

Further objects will become apparent from the following more detailed description of my invention. taken in connection with the accompanying drawing wherein Fig. 1 is an illustrative partial representation, in perspective, showing a bedspring provided with readily mounted and demountable supports.

In itsfundamental aspects, the primary object of my invention is achieved by a bedspring support which comprises a yoke that is adapted for mounting over a bedspring rail, a leg, supporting said rail and adapted to be engaged by the yoke, and means for clamping the yoke, the leg and the rail in rigid assembled relationship.

Referring now to the drawings, and particularly with reference to Fig. 1 and its associated figures, the numeral designates a bedspring, the frame of which comprises a. rail 22. To this rail there is rigidly aflixed or clamped a demountable support 24 which comprises a yoke 2t of metal or other suitable materialand a rail supporting leg 28 of wood. orother appropriate material, said leg and the short sides of the yoke being adapted for engagement with each other.v The whole assemblage of the yoke 26, the rail 22 and the leg 28 are tightly held together by fastening means 30 or other appropriate clamping device.

In this instance the rail 22. is formed ofv an angle iron 32 having a vertical member 34 and a horizontal member 36. The le 28 is provided with a vertical slot 38 intowhich the vertical member. 34 of the rail is fitted. The horizontal member 36. of the rail rests upon the upper surface 40 of the leg 28. The yoke 26 comprises the base 42 and the legs 44 and .46, the latter terminating in iii-turned wings lllfand 5n respectively which are engaged by the horizontal slots .52 and respectively of the leg 28. The base .42 is providedwith a. threaded aperture 56 which is adapted to receive the thumb-screw 58 of the clamping means 36 or other appropriate device, the thumb-screw being tightened against the horizontal member 36 of the angle iron. When four of such legs are afiixed to the rail, two on each side, there is provided a sturdy structure which is adapted to function, by the use of a mattress or similar device, both as a seat and as a bed.

In the modified form of the bedspring support illustrated in Fig. 6 the yoke, instead of being a unitary piece as illustrated in Fig. 4, comprises a base plate 60 and two side members 6?. and 64. The side members are provided with slots 66 and 68 respectively through which the ends 10 and 12 of the base plate protrude, thus bridging the side members. The side members 62 and 64 are bored as at 74 to permit of the insertion of means for fastening the side members to the leg I6 as by wood-screws 80 or the like. The leg 16 is provided with a vertical slot 82 for the reception of the vertical member 34 of the angle rail. The base plate 6!] is provided, in a manner similar to the base 42, with a threaded aperture 84 into which is set the thumb-screw 36, thus providing for the clamping of the assemblage of the yoke, the rail-supporting leg, and the rail in rigid relationship upon the tightening of the thumb-screw.

This form of structure may be assembled by affixing the side members 62 and 64 to the upper portion of the leg 16, leaving suflicient room to allow the slots 66 and 68 thereof to' extend above the upper surface of the le and allow for setting the vertical member of the angle rail within the slot 82 and allow for the insertion of the bridging plate 66, the ends thereof being engaged by the slots. Upon insertion and tightening of the thumb-screw the entire assemblage will be rigidly clamped.

In the embodiment illustrated in Figs. 8 and 9 the yoke of the spring support comprises a structure which is in part a combination of (a) the structure of the yoke illustrated in Fig. 4

and (-b) the structure illustrated in Fig. '6. In

this modification the base of the yoke comprises a a horizontal member 90 and an integral side consisting of the vertical member 92 which terminates in an in-turned wing 94 The other side of the yoke is formed of a plate 96 havin a slot 98 for the reception and engagement of the end I00 of the horizontal member 90. The plate is bored as at I 62 for the reception of screws I I34 or other similar devices whereby said plate may be afiixed to the leg III]. Th leg III) is provided with a vertical slot I I2, similar to the, corresponding slots of the legs illustrated in Figs. 4 and 6, for the reception of the vertical member of the rail angle. One side of the leg is provided with a horizontal slot II 4 within which is engaged the wing 94. The base 90 is provided with a threaded aperture II6 into which may be inserted a thumb-screw I I8 or other similar'device for the rigid clamping of the yoke, the leg and the rail.

wing 94 securely positioned within the horizontal slot II4. Thereupon the thumb-screw H8 is tightened against the horizontal member of the angle rail and the bedsprin support thus securely clamped to the bedspring rail.

As shown in Fig. 10 and its associated figures, the numeral I56 designates a form of bedspring in which the frame comprises a tubular rail I532. The bedspring support I54 comprises a yoke I56, mounted over the rail I52, and a tubular leg I58 on which the rail rests, held, in threaded engagement, within a plate which bridges the sides or legs of the yoke.

The yoke I56 formed of metal or other appropriate material comprises a base I6S and sides or legs I62 and I64, the latter being provided with slots I66 and I68 respectively through which pro trudes a plate I'Ill bridging said sides and being supported thereby. The ends I12 and I74 of the plate I10 may be of such length as will securely effectuate the bridging. The plate Ill is provided with a threaded bore I16 adapted to receive the upper end of the tubular leg I58, threaded as at I18. The base I66 of the yoke is provided with apertures I86 into which may be inserted means such as a set-screw or thumb-screw I82 for rigidly tightening the yoke against the upper side of the rail I52, In affixing this form of support to the bedspring the yoke I56 is laid upon the rail I54. Then the bridging plate I10 is inserted within the slots I66 and I66 so as to be held in engagement thereby and the tubular leg I58 is screwed into the bridging plate H4 and it may be tightened until it securely engages the rail I54. In order to provide a broader supporting surface for the rail I52, a bearing member or pillow block I86 may be used. The base I88 of such bearing member may be set within the upper hollow end of the tubular leg I58, and the rail then rested upon the bearing surface I90 of said pillow block. Then for the better clamping of the rail I54, the tubular leg I58, and the yoke, the screws I82 are tightened until the desired rigidity of the assemblage is attained. The lower end of the tubular le I58 may be fitted with a rubber or other appropriate device It will be understood that the form of support thus described may also be used to support a bedspring in which the rail is an angle, as shown in Fig. 1 and the associated figures, instead of the tubular rail shown in Fig. 10 and the associated figures. In such case the horizontal member of the angle rail lies directly on the top of the tubular leg I58 (the bearing member I86 being removed) while the vertical member of such angle rail may lie against the tubular leg, and the base I66 of the yoke lies on the horizontal member of the angle rail. Such an assemblage is held in rigid relationship by tightening the screws, set within the base of the yoke, against the upper surface of the horizontal member of theangle rail. I

It will be observed that my invention makes it possible for a person quickly and easily to aflix my novel supports to the frame of a bedspring so that the same may be used for the purposes indicated. It will also be obvious that if it is desired to disassemble the erected structure, the same may be done speedily without the use of any special tools. Furthermore, if it is desired to provide for extreme sturdiness or rigidity, there may be used,v in addition to the four corner legs normally used, any additional number of supports appropriately positioned underneath the bedspring.
